Abstract

The hypothesis of steady epithelial current in an electrically biased sensory epithelium was examined in Plotosus electroreceptors. The in situ conditions were simulated reversibly by electronic shunting of isolated receptors. The epithelial current had an N-shaped property due to Ca current superimposed over passive bias current, with net current close to zero when unstimulated. The high-gain synaptic transfer proved to be the result of modulation of steady Ca component.

摘要

在豹鲇电感受器中检验了电偏置感觉上皮中稳定上皮电流的假说。通过对分离的感受器进行电子分流可逆地模拟原位条件。上皮电流具有N形特性，这是由于钙电流叠加在被动偏置电流之上，在未受刺激时净电流接近零。高增益突触传递被证明是稳定钙成分调制的结果。
